What should I do if a pregnant woman vomits blood? How many weeks does it usually take for a pregnant woman to give birth?

Some pregnant women will experience vomiting blood during pregnancy, which is a very special phenomenon. There are many reasons for pregnant women to vomit blood, such as gastrointestinal bleeding, severe morning sickness, etc. So what should pregnant women do if they vomit blood? How many weeks does a pregnant woman usually give birth?

What to do if a pregnant woman vomits blood

Generally, the most common reason for pregnant women to vomit blood is excessive early pregnancy reaction. Severe vomiting will cause bleeding caused by tearing of the capillaries in the esophageal wall. Generally, the amount of bleeding is small and the duration is short. Don't worry or be afraid. If there is excessive early pregnancy reaction, you can take vitamin B6 and vitamin B1 to relieve vomiting symptoms. Pay attention to adjusting your mentality, avoid eating spicy, greasy, and cold foods, and eat light, warm, and easy-to-digest foods. Eat small meals frequently. Go to the hospital regularly to check the development of the fetus. If the amount of vomiting blood is large, you need to go to the hospital for timely treatment to rule out other lesions such as esophagitis, gastritis, and gastric ulcers.

Note:

The situation of vomiting blood in pregnant women is more complicated and cannot be judged by yourself. It should be taken seriously. It is best to go to the hospital for examination. If it is caused by gastrointestinal diseases, the primary disease should be actively treated. If it is caused by severe morning sickness, you should pay attention to eating small meals and taking anti-emetic drugs when necessary to avoid long-term vomiting that may affect the blood vessels in the stomach, throat and other parts.

How many weeks does a pregnant woman usually give birth?

Since it is difficult for every pregnant woman to accurately determine the time of conception, medical regulations stipulate that the expected date of delivery is calculated from the first day of the last menstrual period. The entire pregnancy period is 280 days, or 10 gestation months (each gestation month is 28 days).

The due date is the date when a pregnant woman is expected to give birth. The due date is not the exact date of delivery. Scientists have calculated that only about 5% of women give birth on the due date.

Pre-production calculation method

(1) Calculated based on the last menstrual period:

Add 9 or subtract 3 from the month of the last menstrual period to get the month of the expected delivery date; add 7 to the day of the last menstrual period to get the day of the expected delivery date.

For example: The last menstrual period was on February 1, 1985, month 2 + 9, day 1 + 7, due date = November 8 (1985)

The last menstrual period was April 15, 1985, month 4 - 3, date 15 + 7, due date = January 22 (86)

(2) Calculated based on the date of fetal movement:

If you can't remember the date of your last menstrual period, you can calculate it based on the date of fetal movement. Generally, fetal movement begins 18-20 weeks after pregnancy.

The calculation method is: for primiparas, it is the day of fetal movement plus 20 weeks; for multiparas, it is the day of fetal movement plus 22 weeks.

(3) Calculated based on the basal body temperature curve:

The last day of the low temperature segment of the basal body temperature curve is regarded as the ovulation day, and the ovulation day is counted back 264-268 days, or 38 weeks.

(4) Calculation based on B-ultrasound examination:

Doctors can estimate the gestational age by measuring the biparietal diameter, crown-rump length, and femur length during B-ultrasound.

And calculate the expected date of delivery (this method is mostly used by doctors for B-ultrasound diagnosis).

(5) Calculation from the time morning sickness starts:

Morning sickness usually occurs at the 6th week of pregnancy, which is 42 days after the last menstrual period. The expected date of delivery is 280 days after the last menstrual period.

(6) Roughly estimate based on the height of the uterine fundus

If you can't remember the date of your last menstrual period, you can roughly estimate the due date based on the height of the uterine fundus.

The height of the uterus is between the navel and the upper edge of the pubic bone (10 cm above the pubic symphysis);

At the end of May of pregnancy, the uterine fundus is 2 horizontal fingers below the navel (16-17 cm above the pubic bone);

At the end of the sixth month of pregnancy, the uterine fundus is level with the navel (19-20 cm above the pubic bone);

At the end of the seventh month of pregnancy, the uterine fundus is three horizontal fingers above the navel (22-23 cm above the pubic bone);

At the end of the eighth month of pregnancy, the xiphoid process of the uterine fundus is in the middle of the umbilicus (24-25 cm above the pubic region);

At the end of the ninth month of pregnancy, the uterine fundus is 2 horizontal fingers below the xiphoid process (28-30 cm above the pubic bone);

At the end of the tenth month of pregnancy, the height of the uterine fundus returns to the height at eight months, but the abdominal circumference is larger than at eight months.

How to exercise during pregnancy

Walking: You can take a walk every morning after getting up and after dinner. The time and distance of the walk can be adjusted according to your own feeling, so as not to feel tired. Don't walk too fast when walking, but walk slowly to avoid too much vibration or fatigue. Pay special attention to this in the early and late stages of pregnancy.

Radio gymnastics: Radio gymnastics is also a suitable exercise method for pregnant women. You can do a few sessions every day after taking a walk or during work breaks. Don't get too tired every time, and stop when you sweat a little.

Doing gymnastics for pregnant women: There are many benefits to doing gymnastics for pregnant women. It can prevent back and leg pain caused by weight gain and changes in the center of gravity; it can relax the muscles of the waist and pelvis, preparing for the smooth passage of the fetus through the birth canal during future delivery; it can also enhance self-confidence, so that you can calmly cooperate with the doctor during delivery and ensure the safe birth of the fetus. When doing gymnastics, the movements should be light and gentle, and the amount of exercise should be appropriate without feeling tired.

Is it better for a pregnant woman to have a hard or soft belly?

Whether a pregnant woman's belly is hard or soft depends on her physical condition. The situation of each pregnant woman is different, so as long as the fetus is healthy, it's fine.

It is normal for pregnant women to have a hard belly, so don't worry. This is because the fetus grows rapidly in the late pregnancy, the uterus enlarges, and the belly does not grow as fast as the uterus. The uterus will hold the belly tightly, and the fetus will move more vigorously, so the belly will become hard. Pregnant women only need to pay more attention to the frequency of fetal activity and check the development regularly.
